Fluoride
Found naturally in some foods such as tea, fish, vegetables and fruit juices, Fluoride's inclusion into toothpaste has been a major public health advance.
Fluoride has been the major factor in reducing the incidence of dental decay and has been used in toothpastes for almost 50 years.
It works by promoting a chemical reaction in tooth enamel that draws in replacement minerals including calcium. Fluoride incorporates itself into enamel weakened by acid attack, making the tooth more resistant to future acid attacks.
